Parameters
- anyOf
Type: array<System. . :: . .Char> [] () [] []
A Unicode character array containing one or more characters to seek.
- startIndex
Type: System. . :: . .Int32
The search starting position.
- count
Type: System. . :: . .Int32
The number of character positions to examine.
Return Value
Type: System. . :: . .Int32
The zero-based index position of the first occurrence in this instance where any character in anyOf was found; -1 if no character in anyOf was found.
Remarks
The search begins at startIndex and continues to startIndex + count -1. The character at startIndex + count is not included in the search.
Index numbering starts from zero. The startIndex parameter can range from 0 to one less than the length of the string instance.
The search for anyOf is case-sensitive.
